The ontology distinguishes a source, a fixed snapshot of that source, a relevant fragment and the claim supported by it. It also represents conflicts and editorial decisions. A simplified research view can then remain connected to the richer account behind it.
Time and context are not optional decoration
A component’s role or an instrument’s configuration can depend on a historical state. An assertion’s applicability can depend on context. If the scope is not known, it should not silently become universal.
Validate the model, review the interpretation
OWL distinctions and SHACL constraints help catch incompatible identities and malformed data. They complement, rather than replace, source criticism and organological judgement.
